Hero Glamour XTEC Variants

The Performace of the Bike has been seemed to have been Good. The Bike is almost a Comfort & Damdaar, but when it is accelerated beyond 45 - 50 km Long-drive seen stressed. The Engine starts making a stressed Noice which feels the Rider irritated. The Bike needs increase in Engine cc Level. Otherwise, it is Good though it has no Market preferably in terms of its present Look. If the cc upgraded and a MOST Attractive Look given, the Bike would have been NO Challenge even it's Market would also be increased, the then Time will automatically say. Thanks !
